Not sure what to say here except, I do not like cheating and exploiting. This might be one of the most blatant exploits I've seen before and it's not only wildly inappropriate to lore, it's also game-breaking in PvP. I have seen players with BOTH vampire and werewolf as active skill lines. I have been away for a while and I come back from a short hiatus and on seeing this, thought "Oh my god, has Zenimax lost it's mind?" But no... it's an exploit and the players who described it to me are clearly aware it is.
Devs, I'm looking to you to crack down on this. Honest players do not wish to see this in the game nor deal with it in PvP. I guess those who have done it have kept it mildly quiet but it wasn't hard to search the web for the instructions. Some responses here would not hurt either.
I'll not post the instructions here for the sake of avoiding others performing this exploit more than is already done but, I can show you should you need to in PMs, thought I should think you may already know.
Thank you.
